Mitch Carson is a S. H. I. E. L. D. security agent under Dum Dum Dugan and someone whom Eric O'Grady looks up to. During the "Enemy of the State" story, Wolverine attacks the S. H. I. E. L. D. Helicarrier and Mitch order Eric and his roommate Chris McCarthy to guard Hank Pym and the new Ant-Man suit. Pym walks out and they panic and knock him out. McCarthy accidentally runs off with the suit to escape Wolverine, but later when Elektra attacks the Helicarrier a month later Eric finds McCarthy and steals the suit from his dead body, after being shot by a HYDRA agent. Instead of returning the suit, he steals stuff, peeps on the woman's showers and tries to seduce, and accidentally impregnate McCarthy's girlfriend. Carson, originally trained to be the stolen Ant-Man suit's wearer, was forced to wear a hastily built prototype suit and track down the thief. Carson is able to track down O'Grady, but in the ensuing battle, Eric disfigured Carson's face by accident with his suit's jets, burning the left half of Carson's face and leaving Carson deaf and blind on that side as well. O'Grady took Mitch to the infirmary nearby to help the injured Mitch, but he still vowed revenge.
